Application:
Double pilot check valves allow free flow in a direction (with low pressure drops);
They stop in the opposite direction until they are opened by the pilot pressure(coming from the other line of the circuit)
Specification:
Materials: zinc-plated carbon steel body
Seals: standard in nitrile NBR. On request FKM,EPDM seals
Working temperature: with standard seals -25℃ + 125℃
